Each redundant call\ncorrupts the anchor's doubly-linked list and inflates the URB\nrefcount. When usb_kill_anchored_urbs() traverses the list during\nstream stop / suspend / disconnect, the corrupted list leads to\nuse-after-free.\n\nRemove the redundant usb_anchor_urb() from the resubmit path.","published":"2026-08-06T08:16:36.000Z","lastModified":"2026-08-17T05:18:07.000Z","status":"Received","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":{"version":"3.1","score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"cwe":[],"affected":[],"epss":{"score":0.00168,"percentile":0.0614,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.17%).
